Description

Technical Field

[0001] The utility model relates to the technical field of HDPE bottles, in particular to a high-density medical HDPE bottle with compression resistance. Background Technique

[0002] In the medical field, high-density polyethylene (HDPE) bottles are widely used in the packaging of drugs, biological products, and medical devices due to their excellent corrosion resistance, chemical stability, and processing performance.

[0003] However, traditional HDPE bottles are prone to deformation or even rupture when facing external pressures (such as extrusion and dropping during transportation). This not only may lead to the contamination or invalidation of drugs but also may pose safety hazards to users. In addition, some drugs are sensitive to temperature and require good heat insulation performance to maintain their stability, while traditional HDPE bottles perform poorly in this regard.

[0004] To solve the above problems, although there are already some designs in the prior art to enhance the compression resistance of HDPE bottles, such as increasing the wall thickness and using reinforcing ribs, these methods often sacrifice the lightweight characteristics of the bottles, increase the manufacturing cost, and have limited effects on improving the heat insulation performance. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-density medical HDPE bottle with compression resistance to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A high-density medical HDPE bottle with compression resistance, including a bottle body, a bottle cap is sleeved and screwed at the bottle mouth of the bottle body.

[0009] Preferably, an embedding groove I is formed in the top surface of the bottle body, and an embedding groove II is formed in the bottom surface of the bottle body. Both the embedding groove II and the embedding groove I are annular grooves. Both the compression sheet I and the compression sheet II are in the shape of an annular plate. The compression sheet I is fixed inside the embedding groove I, and the compression sheet II is fixed inside the embedding groove II. The thickness of the compression sheet I is equal to the height of the embedding groove I, and the thickness of the compression sheet II is equal to the height of the embedding groove II.

[0010] Preferably, an embedding groove III is formed in the outer wall of the bottle body. The embedding groove III communicates with the embedding groove I and the embedding groove II. The support sheet is in the shape of an arc-shaped strip. The support sheet is fixed inside the embedding groove III, and the thickness of the support sheet is equal to the depth of the embedding groove III.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The high-density medical HDPE bottle with compression resistance proposed by the present utility model integrally forms an inner liner inside the bottle body to form a compression-resistant cavity, effectively dispersing the external pressure and significantly improving the lateral compression resistance of the bottle body. In addition, the compression-resistant framework composed of the compression sheet I, the compression sheet II and the support sheet is sleeved on the outer wall of the bottle body, further enhancing the overall compression strength of the bottle body, and maintaining a stable shape even under high-intensity pressure to prevent cracking; the cavity between the bottle body and the inner liner not only enhances the compression resistance, but also naturally forms a heat insulation space, effectively reducing the influence of the external temperature on the medicine in the bottle, and is particularly suitable for storing temperature-sensitive medicines.

[0021] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: a high-density medical HDPE bottle with pressure resistance, including a bottle body 1. An inner liner 2 is integrally formed inside the bottle body 1. The top end of the inner liner 2 is inserted into the bottom end of the bottle mouth of the bottle body 1, and the outer diameter of the top surface of the inner liner 2 is equal to the caliber of the bottle mouth of the bottle body 1. A gap is reserved between the top surface of the inner liner 2 and the top surface of the bottle body 1, and a cavity is reserved between the bottle body 1 and the inner liner 2. The reason for installing the inner liner 2 inside the bottle body 1 is to reserve a pressure-resistant cavity between the bottle body 1 and the inner liner 2, which not only improves the lateral pressure resistance of the bottle body 1, but also realizes reserving a heat insulation space between the bottle body 1 and the inner liner 2, and even if the bottle body 1 is damaged, the medicine inside the inner liner 2 will not be affected.

[0023] A bottle cap 3 is sleeved and screwed at the bottle mouth of the bottle body 1. External threads are provided on the outer wall of the bottle mouth of the bottle body 1, and internal threads are provided on the inner wall of the bottle cap 3.

A notch 11 is opened on the bottom surface of the dial piece 10, and the width of the notch 11 is greater than the distance between the outer wall of the bottle cap 3 and the inner ring opening of the first pressure-resistant piece 7. The reason for installing multiple dial pieces 10 on the outer wall of the bottle cap 3 is that it is convenient for fingers to dial the dial piece 10 to make it more labor-saving when screwing the bottle cap 3 to rotate. And after the bottle cap 3 is tightened at the bottle mouth of the bottle body 1, the bottom surface of the dial piece 10 presses the first pressure-resistant piece 7, that is, when the top of the bottle cap 3 is pressed, the dial piece 10 directly transmits the pressure to the first pressure-resistant piece 7, so that the pressure-resistant framework composed of the first pressure-resistant piece 7, the second pressure-resistant piece 8 and the support piece 9 bears the load, avoiding the bottle body 1 from being damaged due to pressure.

[0024] The top surface of the bottle body 1 is embedded with a first pressure-resistant piece 7, and the bottom surface of the first pressure-resistant piece 7 is embedded with a second pressure-resistant piece 8. A plurality of support pieces 9 are embedded on the outer wall of the bottle body 1, and the support pieces 9 are fixed between the first pressure-resistant piece 7 and the second pressure-resistant piece 8. An embedding groove one 4 is formed on the top surface of the bottle body 1, and an embedding groove two 5 is formed on the bottom surface of the bottle body 1. Both the embedding groove two 5 and the embedding groove one 4 are annular grooves. Both the first pressure-resistant piece 7 and the second pressure-resistant piece 8 are in an annular plate-like structure. The first pressure-resistant piece 7 is fixed inside the embedding groove one 4, and the second pressure-resistant piece 8 is fixed inside the embedding groove two 5. The thickness of the first pressure-resistant piece 7 is equal to the height of the embedding groove one 4, and the thickness of the second pressure-resistant piece 8 is equal to the height of the embedding groove two 5.
